A total of 663 candidates who were citizens of the United States at time of entry into a medical school outside of the United States or Canada took the January 1974 ECFMG examination. Of these candidates, 237 (35.7%) passed the examination. This compares with a worldwide pass rate of 40.7% for all 18,765 candidates in that examination. It was found that candidates in the last two years of medical school were more successful than those who had already graduated, and that the highest pass rate was found among those taking the examination for the first time. Because of factors such as changes in the curricula of foreign schools, considerable shifts in student populations among the various schools were observed.
